Ironed Glen Turquoise

#4ddbd3
Notes

Ironed Glen Turquoise (#4DDBD3) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (177°, 66%, 58%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Ironed
adjective

Old English īsern, iron — past-participle of iron. As a color modifier, ironed implies a clear-and-smoothed-and-pressed quality, the crisp color of Mid-Century-Modern freshly-ironed-shirt-and-trouser dress-attire textile finish. Sits at the crisp-and-finished end of the grid, parallel to pressed and starched in usage.

Glen
modifier

Scottish-Gaelic gleann, narrow valley between hills. As a color modifier, glen implies a sheltered-and-mossy quality, the visual register of Scottish-Highland deep-cut river-valleys with peat-water-and-bracken hand-cut shieling-and-bothy crofting-life surfaces under Highland-and-overcast sky. Sits at the modifier-and-place end of the grid, parallel to vale and dell in usage.

Turquoise
noun

The hydrated copper-aluminum phosphate mined in Persia and the American Southwest for thousands of years — the firuze of Iran, the chalchihuitl of Mesoamerica, the heart of Pueblo and Navajo silverwork. The color refers to a fine Sleeping Beauty turquoise from Arizona: a saturated, slightly green-shifted blue with the slight matrix of host-rock veining. Brighter than persian, lighter than cerulean.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
